Method for fastening of elastomeric or insulating materials between two structural components

ABSTRACT

In a method for fastening of elastomeric or insulating materials, for instance an elastic mat, provided between two structural components whereby one of the structural components is produced on site after the elastomeric or insulating material has been inserted, the upper shank of a Z-shaped elastomer section consisting of two vertical shanks and a horizontal web is fastened by nails or the like to an already finished structural component, while the lower shank of the elastomer section reaches over the elastomeric or insulating material and then a cover element is fitted over the head of each nail or the like and after that an elastic cord is fitted onto the elastomer section. Finally, the second structural component is produced, whereby the elastomeric or insulating materials, the elastomer section, the cover element and the elastic cord serve as a disposable form.

FIELD OF THE INVENTION

The invention relates to a method for fastening of elastomeric orinsulating materials, for instance an elastic mat, between twostructural components whereby one of the structural components isproduced on site after the insertion of the elastomeric or insulatingmaterials.

THE RELATED ART

In order to fasten elastomeric or insulating materials between twostructural components, up to now sections of rigid synthetic material ormetal have been used. However, these materials create sound conductorsbetween the two structural components.

It is the object of the invention to create a fastening system whichinsures a secure fastening of the elastomeric or insulating material andat the same time has a decoupling effect on vibrations which may occur.

SUMMARY OF THE INVENTION

The solution to the problem consist in a method of the above-mentionedkind, whereby the upper shank of a Z-shaped elastomer section formed bytwo vertical shanks and one horizontal web is fastened by nails or thelike to the already finished structural component, while the lower shankof the elastomer section reaches over the elastomeric or insulatingmaterials and whereby then a cover element is fitted over the head ofeach nail or the like and after that an elastic cord is fitted on top ofthe elastomer section. Finally the second structural component isproduced, whereby the elastomeric or insulating material, the elastomersection, the cover element and the elastic cord serve as a disposableform. The cover element prevents contact between the still fluidconcrete and the nails or the like during the production of the secondstructural component, since at this contact points sound conductors canform.

By the method of the invention the transmission of vibrations from onestructural component to another is completely eliminated. Furthermore,an elastic sealing of the gap between the two structural componentsresults, so that horizontal as well as vertical motions of the twocomponents can be elastically taken up.

In an embodiment of the invention the cover element is designed like acap surrounding the washer provided under the head of each nail or thelike.

In a further embodiment of the invention the used elastomer section hasat its upper shank a horizontal flange,which together with thehorizontal web forms a chamber for receiving the cover element, wherebythe cover element is U-shaped and arranged in such a manner that in themounted state the webs of the U-section face the elastomer section.

According to a further feature of the invention, the horizontal flangeas well as the horizontal web are each provided with a ridge reachingbehind the cover element.

In a particularly simple embodiment of the method of the invention theused elastomer section has at its upper shank a horizontal flangewhereupon a cover element is formed.

Suitably, on the upper shank of the elastomer section an elastic cord isformed.

DETAILED DESCRIPTION

In the embodiment example shown in FIG. 1 the upper vertical shank 1.oof a Z-shaped elastomer section 1 consisting of two vertical shanks 1.oand 1.u and horizontal web 1.m is fastened by nails 2 or the like to thefinished structural component 3, while the lower shank 1.u of theelastomer section 1 reaches over an elastic mat 4. The elastomer profile1 has on its upper shank 1.O a horizontal flange 1.F, which togetherwith the horizontal web 1.m of the elastomer section 1 forms a chamberfor receiving the cover element 5. On the upper shank 1.o of theelastomer section 1, respectively on the flange 1.F, an elastic cord 6is fitted, which extends up to the surface of the structural component3. The second structural component 7 is produced on site by using theelastic mat 4 , the elastomer section 1, the cover element 5 and theelastic cord 6 as a disposable form.

In FIG. 2 an embodiment example basically corresponding to FIG. 1,wherein the flange 1.F and the horizontal web 1.m of the elastomersection 1 each have a ridge 8 which reaches behind the cover element 5.

In the embodiment example shown in FIG. 3 on the upper shank 1.o of theelastomer section 1 an elastic cord 6.1 is formed.

FIG. 4 shows an embodiment example wherein on the flange 1.F of theelastomer section 1 a cover element 5.1 is formed.

The embodiment example represented in FIG. 5 shows a fastening systemwherein the cover element 5.2 is designed like a cap surrounding thewasher 9 provided under each nail 2.
